摘要： 用不同模板剂合成出不同硅铝比的ZSM-5沸石分子筛。在560℃赶除模板剂,经饱合吸冰后,应用多晶X射线衍射测定各样品的结晶度和晶胞体积。实验结果表明,合成氧化铝含量相同的ZSM-5分子筛时,加入不同的模板剂所得分子筛的晶胞体积不等(或称孔体积不等)。据此可以推测,模板剂对合成分子筛的造孔起支撑和定位的作用。

Abstract: The ZSM-5 type zeolite molecular sieves of different Si/Al ratios were synthesized with different templates. After driving out the templates at 560℃, the samples were saturated with adsorbed water, and then the crystal-linity and the volume of cell were determined by X-ray diffraction for poly-crystalline materials.It was discovered that the volumes of cell were linear with content of A12O3weight percent for a series of molecular sieves of the same template but the slope and intercept of lines were unlike for samples of unlike templates, that is,volume of cell or pore volume of the samples of unlike templates were unequal in case of same content of A12O3weight percent. Therefore, it may be deduced that templates play a support and location role in crystalline of molecular sieves for making pore.
